what is the best custom rom and kernel for the xperia play, i have the r800i and it has unlocked bootloader

I'm not sure if you're interested anymore about this question, judging from your post date, but I'll try to help anyway.or if anyone else is curious.

If you're looking for the best game play features your device has to offer with full touchpad support, go for a gingerbread based ROM. The roms below work great for emulators as well as other downloadable games like GTA and are super stable and fast.

If you care more about having the latest Jellbean features with less emphasis on gaming than these JB based roms are excellent. Touchpad support is a problem, but emulators work fine and most downloable games run at a decent pace. Stability and speed can sometimes be an issue, but this is rarely an issue.

I bought my Xperia Play for gaming, so I'm searching a ROM that improves hardware performance.
Yesterday I installed my first custom ROM, a ICS ROM. It's really cool but ICS slows down games and emulators.
What is the best gaming ROM?
I looked the GB ROMs linked by Mayorse (NXT and Gin2JellyBean), what do you recommend?
